THEODORE REYMAN, OF NEV YORK, N. Y.

ELECTRIC-ARC LAM P.

SPECIFICATION forming part of Letters Patent No. 557,606, dated April '7, 1896.

Application filed July 9, 1895. Serial No. 555,419. (No model.)

To all whom, it may concern:

Bc it known that I, THEODORE REYMAN, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Arc-Lights, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof, in which similar letters of reference indicate corresponding parts.

This invention relates to arc-lights, and the object thereof is to produce means for automatically feeding the upper carbon; and with this object in view the invention consists in the construction, combination, and arrangement of parts hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which- Figure 1 is a central vertical section of the body or casing of an arc-light, showing my improved mechanism for supporting and feeding the upper carbon; and Fig. is a plan view of a part of said mechanism.

In the practice of my invention I employ a casing A, in which is placed a series magnet B and a shunt-magnet C, each of which is of the usual construction, and each of which is provided with the usual electrical connection. The supports D extend downward and are connectedwith the lower portion of the lamp (not shown) in the usual manner, these elements forming no part of this invention.

Connected with the upper portion of the casing A, which is preferably cylindrical in form, is a tube E, the upper end of which is closed by a cap e, through the central portion of which is a perforation or opening` e', which is closed by a hinged plate F, which is adapted to open outwardly, as hereinafter described.

W'ithin the tube E is mounted a sliding piston G, with which is connected a rack-bar g, which extends downward and through the casing A, and this bar is adapted to carry at its lower end the upper carbon, as is usual in this class of devices.

Connected with the bottom of the casing A, near one side thereof, are vertical standards a, and pivotally lconnected with the top thereof is a frame H, consisting of the ends 7L and the sides h', and extending centrally through said frame and mounted in the sides thereof is a shaft L, on which is mounted a wheel M. Mounted also on said shaft is a pinion m, provided with longitudinal gear-teeth, as shown in Fig. 2, and a ratchet-wheel N, and a pawl n, pivotally connected with the wheel M, is adapted to operate in connection with said ratchet-wheel, as hereinafter described.

Suspended from the top of the casing A is a hanger O, with the lower end of which is pivotally connected a bar P, with one end of which is connected an armature p, which eX- tends downward into the magnet B, and w th the other end of which is connected an armaturep,which extends downward into the magnet C, and also connected with the end of the said bar P, adjacent to the magnet C, is an arm R, which extends downward and is pivotally connected with the frame H, as shown at 1'. a vertical standard S, to the upper end of which is secured a cross-plate s, to the inner end of which is secured a plate-spring F, the opposite end of which is supported by a vertical standard U, connected with the bottom of the casing, and said spring is adapted to bear upon the wheel M and to limit or control the movement thereof under certain conditions, as hereinafter described. As thus constructed, it will be seen that the frame H is adapted to move on its pivotal connection with the standard 0, and that the bar P is also free to move on its pivotal connection with the hanger O and that the said frame H will be operated upon and the free end raised and lowered by the end of the bar P, with which it is connected.

It will be observed that the rack-bar g is in connection with the pinion m and will be fed downwardly thereby, and the said pinion m and ratchet-wheel N are free to revolve independent of the wheel M when the rack-bar g is pushed upward; but in the reverse movement, when the bar g is fed downward, the pinion m revolves with the ratchet and the wheel M, and the downward movement of the rack gis therefore controlled by the platespring P, and the pressure of this spring on the wheel is regulated by the bar P, and the movement of this bar is regulated by the current which passes through the magnet C.

The said frame H is also provided with IOO The object of the aperture e in the top of the tube E is to allow for the egress of the air when the piston G is moved upwardly, as will be readily understood, and also to prevent an inrush of air when the piston G is being fed downwardly, this being accomplished by the hinged plate F, and by this means the operation of the parts hereinbefore described is facilitated.

In the normal position of the parts the free end of the spring T rests upon the standard U and does not contact with the Wheel M, and in this position of the parts the rack-bar g is fed downward by gravity and the weight of the piston G, and this operation will be continued, this being the condition before the current is turned on. The current being turned on, the magnet B attracts the armature p and draws down the corresponding end of the bar I), thus raising' the free end of the frame II, and thus raising the free end of the spring T from the standard U, when the spring and wheel M will come into contact and the downward movement of the rack-bar g will be stopped. The rack-bar g will be held in this position until the burning away of the carbons increases the space between them, when the current through the magnet C will be increased and the armature p drawn down thereby, thus forcing down the free end of the frame II, when the free end of the spring T will come in contact with the standard U and will be fed from the wheel M, when the rack-bar g will again feed the upper carbon downward, and this movement of the parts will continue as long as the lamp is in operation.

It is evident that changes in the form, construction, combination, and arrangement of the various parts of my invention, as shown and described, may be made without departing from the spirit thereof or sacrificing its advantages, and I therefore reserve the right to make such alterations therein as fairly come within the scope of the invention.

Having fully described my invention, its construction and operation, I claim and desire to secure by Letters Patent In an arc-light the combination with a casing having the usual series and shunt magnets, of the vertical tube secured within said casing and screwed thereto, the tubular extension upon the top of said casing and connected with an opening in the casing within said tubular extension, said tube being provided with a cap or covering in which is formed an opening, said cap or covering having a hinge-lid to close said opening, the piston within said tube carrying a rack-bar upon the lower end of which is secured the upper carbon, and the frame pivoted at one end to a vertical standard at one side of said casing, a transverse shaft connected with said frame, upon which is mounted a pinion gearing with said rack-bar, the horizontal bar having pivotal connections with the top of said casing and provided at each end with a depending armature extending into said m agnets,pivotal connections with the free end of said frame, whereby said piston regulates the downward movement of said rack-bar, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 6th day of July, 1895.

TIIEODORE REYMAN.
